GB/T 478 coal drifting Test Method MT/T 320 coal core samples of coal washability test methods3 Evaluation Method3.1 evaluating coal washability a "separation density ± 0.1 Content Act" (referred to as "δ ± 0.1 Content Law"). 3.2 drifting test shall comply with GB/T 478 or MT/T 320's. 3.3 δ ± 0.1 content is calculated. a) δ ± 0.1 content according to the theoretical separation density calculation; b) the theory of separation density in an optional curve is determined (accurate to two decimal places) specified coal ash; C) When the theoretical separation density less than 1.70g/cm3, Shen deduction Refuse ( > 2.00g/cm3) 100% calculated δ ± 0.1 content; Li On the separation density equal to or greater than 1.70g/cm3, the deduction Low Density (< 1.50g/cm3) 100% calculated δ ± 0.1 content; d) δ ± 0.1 content expressed as a percentage, the calculation result after rounding to one decimal place. 3.4 evaluating coal washability may refer to Appendix A of.4 Rating naming and classificationAccording to the degree of difficulty sorting the coal washability divided into five grades, each grade name and δ ± 0.1 content shown in Table 1. Table 1 The classification of coal washability δ ± 0.1 content /% Optional Level ≤10.0 easy to choose 10.1 to 20.0 moderate optional 20.1 to 30.0 is more difficult to choose 30.1 to 40.0 Refractory > 40.0 extremely difficult election ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 16417-2011_English be delivered?Answer: Upon your order, we will start to translate GB/T 16417-2011_English as soon as possible, and keep you informed of the progress.
